아렌자나 데 아리바‬에서 가장 멋진 ‪5‬개의 천연기념물

Wonderful to cycle on the little-used road along the reservoir.

Singular tree of the CCAA, quite deteriorated but enduring the passing of the years.

The Mansilla reservoir is located on the Najerilla river, a tributary of the Ebro river. Its waters hide the old town of Mansilla de la Sierra, whose church and some other buildings are visible when it is low.

The port of Peña Hincada has good asphalt and horizontal signage. It is a road with little vehicle traffic. Shadows abound up to Brieva to disappear from that core to the top, totally stark in its most demanding part. Be very careful if it is done in winter, check the weather beforehand.

This mostajo or rowan is located a few meters from a path that runs through the Sierra de la Demanda. Rowans are small trees that rarely reach fifteen meters in height. However, this is a rowan tree to be highlighted, probably one of the largest known specimens from the Peninsula and surely one of the longest-lived.

The Mansilla Reservoir is a dam that collects the waters of the Río Neila among others, and from where the Sierra de la Demanda is located to the north, and the Picos de Urbión to the south.

The port of Canto Hincado (also called Peña Hincada) owes its name to the menhir found there. In case of need, we have the Peñahincada refuge 200 meters to the west and another refuge, Cantohincada, a couple of kilometers to the east.

They have enabled an area for bathing, ideal after the walk. The water is cool even in summer.
